Building Security System

ABSTRACT

A security system that can be used in a home, office, or other building in order to generate alarms or take other actions depending on conditions within the building. The security system may rely on sensors within the building which sense various conditions and collect other data. The information learned from the sensors can be communicated to a location outside the building for processing, such as, but not limited to, processing associated with a need to instigate an alarm.

BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to building security systems.

2. Background Art

FIG. 1 illustrates a building security system 10 where agateway/security panel 12 within a building 14 processes alarm systeminformation. The panel 12 locally generates an alarm if the alarm systeminformation indicates a suitable security risk. The alarm systeminformation may be derived from a number of sensors 16 positionedthroughout the building 14. The security panel 12 may immediatelygenerate the alarm and/or transmit the alarm to a central monitoringstation 18 for verification. In either case, the need for the alarm isdetermined locally at the building 14.

These local determinations can be problematic, at least, from a serviceand maintenance perspective. Since the gateway/security panel softwareused to assess the need for the alarm resides locally in the building14, any updates or modifications relevant to alarm assessments must bemade at the building 14. This requires the panel 12 to be locallymodified if it is to accommodate new devices and application logic whennew devices, monitoring techniques, or other changes to the buildingsecurity system are desired. This can increase both complexity and costof devices in the building 14 when new monitoring features are added orcurrent monitoring capabilities are adjusted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT(S)

FIG. 2 illustrates a building security system 20 in accordance with oneembodiment of the present invention. The building security system 20 maybe configured to support security-related surveillance and services fora home, office, or other building 22. A security service provider 24,such as a central monitoring station, may communicate with the building22 to support any number of building security processes. The system 20may support security processes that rely on one or more sensors 26, suchas audio, video, temperature, air quality, and presence sensors, tomonitor related conditions within the building 22. Data regarding themonitored conditions can be communicated over a network 28 to a centralmonitoring server 30. While FIG. 2 illustrates an embodiment of theinvention in connection with a building, the invention is not limited toimplementation with a building. By way of example only, the inventioncan be implemented with any number of buildings, a facility or the like.Nor does the type of building(s) or facility(ies) limit the invention.By way of example only, the building(s) and/or facility(ies) could beresidential, commercial or the like.

The network 28 may be any type of wireless or wireline network such as,but not limited, to a high speed data network used by cable televisionservice providers to support cable television signaling and/or othertypes of networks used to support high speed data and non-televisionrelated signaling. The network may be used to support continuoustransmission of data from the sensors 26 regardless of whether themonitored conditions have changed. This stream of data can betransmitted to the central monitoring server 30 for further processing.

The central monitoring server 30 may assess the need to instigate analarm from the information provided by the sensors 26. A gateway 32, forexample a settop box (STB), cable modem, router, and/or other serviceprovider/supported device within the building may be used to communicatethe data collected by the sensors 26 regarding the conditions in thebuilding 22 to the central monitoring server 30. The gateway 32encapsulates or otherwise packages the data provided by the sensors 26for transmission to the central monitoring server 30 without performingsecurity-related processing.

The security-related processing associated with triggering the alarms isperformed by the central monitoring server 30. This alleviatesprocessing demands on the gateway 32. If changes or other updates to thesecurity process are needed, i.e., to support new functionality, homedevices, sensors, etc., the central monitoring server 30 may be updatedinstead of requiring significant updates to the gateway 32.

The central monitoring server 30 may be configured to monitor conditionsin a number of buildings 22 and to separately instigate alarms in eachbuilding 22. Each building 22 may similarly transmit sensed conditionsto the central monitoring server 30 for processing. Because the centralmonitoring server 30 is used instead of the gateway 32 to assess theneed for the alarm, the central monitoring server 30 is updated tosupport updated functionality in each of the buildings 22 withoutrequiring significant updates in the buildings. This can limit the costof updates when the service provider 24 provides additional services tocustomers.

The central monitoring server 30 may include any number of applicationsthat perform any number of security processes, such as, but not limitedto, those associated with elder monitoring, video monitoring, audiomonitoring, medical monitoring, energy management, and/or somecombination thereof.

For example, elder monitoring may include monitoring for movementswithin the building 22 and generating an alarm if movements are notdetermined over a period of time. Video monitoring may use facialrecognition or other techniques to assess whether intruders are withinthe building 22. For example, a video camera 40 may be included tocapture video from within the building 22, and a DVR 42 may beginrecording video when presence detectors sense a presence within a roomwhile the building security system 20 is armed. This video can betransmitted to the server 30 for intruder analysis and/or alarmverification. Similarly, audio monitoring can operate with the videomonitoring to support related security assessments. The information fromany sensor 26 can be used with information from the other sensors 26 toassess the need for an alarm.

FIG. 3 illustrates a flowchart 50 for a method of supporting buildingsecurity in accordance with one embodiment of the present invention. Themethod may be used to instigate any type of alarm and to facilitate anytype of security measure. Instead of detailing each of the numeroustypes of alarms contemplated by the present invention, the describedalarm, or generic alarm, is intended to include any type of alarm. Themethod, without intending to limit the scope and contemplation of thepresent invention, is predominately described with respect to theprocesses used to determine a need to instigate the alarm and otherfeatures associated therewith.

Block 52 relates to sensing one or more conditions within a building 22.This may include the use of any type of sensor 26 to sense any type ofcondition within the building 22. Some of the sensors 26 may be presencesensors that sense the presence of a human or animal, door sensors thatsense whether a door (room, appliance, cabinet, etc.) is opened orclosed, temperature sensors (room, body, etc.), air quality sensors(e.g. carbon monoxide detectors), and the like. The sensors 26 may alsoinclude video, audio, and other multiple media sensors. Each of thesensors 26 are connected to a building network 28 having capabilitiesthat allow the conditions sensed by the sensors 26 to be delivered tothe gateway 32.

Block 54 relates to the gateway 32 transmitting the sensed data to thecentral monitoring server 30. This is done without assessing the need toinstigate or otherwise generate an alarm. Of course, the presentinvention contemplates performing some alarm assessment at the buildingand optionally generating the alarm without reliance or completereliance on the central monitoring server 30. The data may betransmitted over any one-way or two-way wireless (e.g., GSM, CDMA,Wi-Fi, WiMax) or wireline network 28 (e.g., fiber optic, hybrid fibercoaxial, coaxial only, copper pair).

Block 56 relates to determining a need to generate or otherwiseinstigate an alarm. The need to instigate the alarm is determined by thecentral monitoring server 30 based on the information transmitted inBlock 54 and without assessment by the gateway 32. The alarm may be anytype of alarm and may vary depending on the conditions within thebuilding 22. The alarm may be varied over time and in response tochanges in conditions at the building 22, i.e., the urgency of the alarmcan be escalated if conditions change within the building 22.

One type of alarm may be a building-based alarm that requires playbackof an audio alert (siren, message, etc.), actuation of a device (doorlock, fire extinguisher, etc.), or the execution of other operations atthe building 22. Another type of alarm may be a non-building-based alarmthat requires alerting or otherwise communicating with a governmentalservices agency, such as police, fire, medical, or other entity outsidethe building 22. Yet another type of alarm may include some combinationof the building and non-building-based alarms.

Block 58 relates to verifying authenticity of the alarm. Theauthenticity of the alarm may be verified in an effort to combat falsealarms and other inappropriate allocations of resources. In some cases,customers can be penalized if governmental service agencies respond tofalse alarms. The verification process may require the entry of apassword or other security measure to insure an authorized person orentity verifies the need or lack of need for the alarm.

One process for verifying alarm authenticity may require in-buildingverification. The in-building verification may be of the type thatrequires an occupant within the building 22 to verify the necessity ofinstigating the alarm. The central monitoring server 30 may open acommunication channel with the building 22 or, more particularly, withone or more devices in the building 22. The communication may besufficient to control various operations of the device in order torequest an occupant to respond to a verification response message.

One verification request may include displaying a message on atelevision within the building 22. The central monitoring server 30 mayinstruct the STB 34 to display a message on the television 34 thatrequests the occupant to acquiesce to the alarm, such as by selecting abutton on a remote control or on the STB 34. The central monitoringserver 30 may also open a communications session (POTS call, IM session,SMS message, etc.) or VoIP call with a device in the building 22 torequest confirmatory information. The communications necessary to theseoperations and other operations may be carried out over any wireline orwireless network 18, including a cable television network.

Another verification process may include verifying the alarm from otherinformation collected from the building 22. If a fire is detected with afire sensor, for example, the sensors that sense temperature and airquality may be used to verify the fire detected by the fire sensor. Ifan intruder is detected with a presence sensor, for example, video maybe retrieved from the DVR 42 and reviewed by a computer 44 for facialrecognition or played for a human operator to assess the presence of anintruder.

These and other processes of verifying the sensed conditions triggeringthe alarm with other sensed conditions can be helpful if communicationswith the building 22 are lost or otherwise disrupted. Rather thanrelying on communications with the building 22, the central monitoringserver 30 can analyze the information it has already accumulated toverify the need for the alarm. This process can also be helpful if theonly person in the building 22 is an intruder or another individual thatis unwilling or unable to verify authenticity.

Block 60 relates to instigating the alarm. The instigated alarm may varydepending on the events triggering the alarm. The scope, duration,intensity, and other parameters of the alarm may be varied over time.The central monitoring server 30 may adjust or discontinue the alarm ifadditional information is received from the sensors 26 within thebuilding 22 and/or in response to an interrupt. An interrupt may beinstigated if a building occupant's response to the verification requestafter the alarm is instigated and/or if an entity arriving at thebuilding otherwise terminates the alarm.

As supported above, one non-limiting aspect of the present inventioncontemplates a common, extensible protocol for a gateway 32 in abuilding 22 to encapsulate or translate sensor 26 data. This data canthen be sent to one or many application servers 30 that will decode thedata and determine if action needs to be taken based on user-selectedmonitoring criteria. One scenario may include a building 22 that hassigned up for both a building security service and an elder monitoringservice. A motion sensor 26 in the living room can be used to detectmotion in the building 22. The gateway 32 can wrap a data packet fromthe activated motion sensor 26 with a tag that identifies the particularbuilding 22 or gateway 32 and send it to the application server 30. Thedata packet can be received by several, if not all of the applicationservers 30 and used as necessary. The security server 30 can determinethat a motion sensor 26 was activated in the building 22, andoptionally, verify that the building 22 has subscribed to its service.The security server 30 can search its database to verify if the alarm iscurrently armed or disarmed. If the alarm is armed, the security server30 can send a signal to the central monitoring station 24 indicating anintrusion. If it is disarmed, the security server 30 can log the eventand remain inactive. The elder monitoring server 30 can also receive thesame data packet from the building 22 and verify that the building is asubscriber. The elder monitoring server 30 can be configured to notify afriend/neighbor/family member in case there is no “activity” (motion) inthe building 22 for a period of time. Because motion is detected, thecountdown timer can be reset in the elder monitoring server 30. Shouldthe timer reach zero, the alarm notification can be sent.

By building the system 20 in this manner, the gateway 32 can be anextremely inexpensive device or integrated into other devices already inthe building 22. The application can be standard regardless of whatdevices are added to the building 22 or what services are added to thenetwork. Additionally, services may include medical monitoring, audiomonitoring, visual monitoring, or combinations thereof. Additionalfeatures include using the gateway 32, television 34, or internet toactivate or deactivate the security system 20 and using theSTB/television 34, or internet to monitor the building 22 from a remotelocation. Optionally, the STB/television 34, or a displayed supportedthrough an application running on it, may be used to check the status ofany one or more of the sensors 26 at anytime, such as to view video ofparticular areas within the building 22 upon hearing a threateningsound, assess whether a door sensor is detecting a door to be open,assess whether the security system 20 has been armed, etc.

The foregoing is predominately described with respect to activating asecurity related alarm, such as but not limited to illuminating a lightsource, displaying a message, calling an emergency response entity,locking doors, activating a siren or taking other security relatedmeasures. The present invention, however, is not intended to be solimited. The present invention contemplates non-security related alarms,such as alarms used to indicate faults or failures within applianceswithin the home, a need to replace a lighting source, a need to answer adoor, and/or to take action in response to any number of measureableevents occurring within a building or facility. As such, the term‘alarm’ as used throughout the foregoing is intended to encompass anytype of message, transmission, activation, or other responsive eventused to communicate a significant, meaningful, relevant or monitored forchange in status as reflected by one or more sensed conditions.
